Relation Between the Detail of the Beam -to- Column Welded Connections and Plastic Deformabilities with Wide Flats Produced by Electric Furnaces

Abstract

To satisfy the plastic deformabilities at beam-to-column welded connections in the type of site welding with wide flats produced by electric furnaces, the absorbed energy at 0°C should be satisfied over 50J at V-notch Charpy test. 8 specimens for the type of shop welding including the details without scallops are prepared and examined. There are 5 specimens made up the wide flats with low impact tougthness. 1 specimen is fractured owing to weld flaw, however 4 specimens are not fractured and meet the requirement of plastic deformabilities
